A sliding plate is slidably connected inside the groove, and a support plate is fixedly connected to one side of the sliding plate. A hydraulic cylinder is provided at the bottom of the sliding plate, and a fixing plate is fixedly connected to one side of the side plate. This steel support welding device includes a base, side plate, groove, sliding plate, support plate, and hydraulic cylinder. By activating the hydraulic cylinder, the hydraulic cylinder can push the sliding plate upward, allowing the sliding plate to move upward along the groove on the side plate. This facilitates the adjustment of the support plate to a suitable position, thereby facilitating the movement of the steel support on the support plate to a suitable height. This allows for welding of steel supports according to different needs, meeting daily usage needs and bringing convenience to people's daily steel support welding.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: steel workpieces are easily displaced by external forces during welding, resulting in weld misalignment and affecting accuracy; traditional clamping devices are difficult to adapt to the fixing requirements of workpieces of different sizes, thus limiting their applicability. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary fixing steel welding device to solve the problems in the background art where steel workpieces are easily affected by external forces during the welding process, resulting in weld misalignment and affecting accuracy. Traditional clamping devices are difficult to adapt to the fixing requirements of workpieces of different sizes and have limited applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary fixing steel welding device, including a base, wherein two symmetrically distributed adjusting plates are slidably connected inside the base;

[0007] The adjustment plate has a support plate in the middle, and the support plate is an upward arched arc structure. The side of the adjustment plate that is far apart from each other is rotatably connected to a movable roller, and both ends of the base are rotatably connected to fixed rollers. The upper surfaces of the support plate, the movable roller and the fixed roller are on the same horizontal plane.

[0008] Preferably, the adjusting plates are fixedly connected to symmetrically distributed connecting rods on opposite sides, and the movable roller is rotatably connected between the two connecting rods.

[0009] Preferably, the bottom of the base is slidably connected to symmetrically distributed guide rails, and the guide rails are set in pairs.

[0010] Preferably, a first lead screw is rotatably connected in the middle of the base, and the threads at both ends of the first lead screw are in opposite directions. A rotating shaft that is perpendicular to the first lead screw is rotatably connected in the middle of the base.

[0011] Preferably, a worm gear is fixedly connected in the middle of the first lead screw, and a worm is provided in the middle of the rotating shaft, with the worm meshing with the outer side of the worm gear.

[0012] Preferably, a threaded sleeve is fixedly connected to the bottom center of the support plate, and the threaded sleeve is threadedly engaged with the first lead screw. Both sides of the bottom of the adjusting plate are provided with pulleys, and the pulleys are tactilely connected to the upper surface of the guide rail.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: an auxiliary fixing steel welding device, including a base 1, with two symmetrically distributed adjusting plates 2 slidably connected inside the base 1; a support plate 3 is provided in the middle of the adjusting plates 2, and the support plate 3 has an upwardly arched arc structure; a movable roller 4 is rotatably connected to the side of the adjusting plates 2 that is far apart from each other, and fixed rollers 5 are rotatably connected to both ends of the base 1, and the upper surfaces of the support plate 3, the movable roller 4, and the fixed roller 5 are on the same horizontal plane; symmetrically distributed connecting rods 6 are fixedly connected to the side of the adjusting plates 2 that is far apart from each other, and the movable roller 4 is rotatably connected to... Between the two connecting rods 6; the bottom of the base 1 is slidably connected to symmetrically distributed guide rails 7, and the guide rails 7 are set in pairs. Both sides of the base 1 are provided with guide grooves 8, and the two ends of the adjusting plate 2 are slidably connected to the corresponding guide grooves 8 respectively; the middle of the base 1 is rotatably connected to a first lead screw 9, and the two ends of the first lead screw 9 have opposite thread directions. The middle of the base 1 is rotatably connected to a rotating shaft 10 that is perpendicular to the first lead screw 9; the middle of the first lead screw 9 is fixedly connected to a worm gear 12, and the middle of the rotating shaft 10 is provided with a worm 11, and the worm 11 meshes with the outside of the worm gear 12.

[0026] When the device is in use, two steel workpieces are first placed on two support plates 3 respectively, and the steel workpieces are supported by the support plates 3, the movable rollers 4 and the fixed rollers 5. The steel workpieces are fixed by the downward movement of the lower pressure plate 17, so that the top of the support plate 3 and the bottom of the lower pressure plate 17 clamp and fix the steel workpieces.

[0027] Once the steel workpiece is fixed, the first lead screw 9 rotates to drive the two threaded sleeves 13 to move. The threads at both ends of the first lead screw 9 are in opposite directions. The first lead screw 9 will then drive the two threaded sleeves 13 to move synchronously in opposite directions, causing the threaded sleeves 13 to move the two adjusting plates 2 closer to each other. The two ends of the adjusting plates 2 will slide inside the guide groove 8 until the weld joints between the two steel workpieces are aligned, facilitating subsequent welding operations. At this time, the remaining parts of the steel workpiece between the support plate 3 and the lower pressure plate 17 will be supported by the movable roller 4 and the fixed roller 5 respectively, preventing the steel workpiece from shifting due to uneven force. The movable roller 4 moves with the adjusting plate 2 during the movement of the adjusting plate 2. Therefore, when the steel workpiece is small, it can be aligned and supported individually by the movable roller 4.

[0028] During the rotation of the first lead screw 9, the rotation of the shaft 10 drives the worm gear 11 in the middle to rotate, and the rotation of the worm gear 11 drives the worm wheel 12 to rotate. At this time, the worm wheel 12 will drive the first lead screw 9 to rotate, thereby achieving the driving effect on the threaded sleeve 13. During the movement of the threaded sleeve 13 and the adjusting plate 2, the two pulleys 14 installed at the bottom of the adjusting plate 2 will roll on the top of the guide rail 7. Since the support plate 3 has an upwardly arched arc structure, the pressure on the support plate 3 will be distributed to the pulleys 14 and both ends of the adjusting plate 2, thereby dispersing the direct pressure of the lower pressure plate 17 and the steel workpiece on the support plate 3.

[0029] Example 2: Based on Example 1, the following structure is also disclosed: A threaded sleeve 13 is fixedly connected to the bottom middle of the support plate 3, and the threaded sleeve 13 is threadedly engaged with the first lead screw 9; both sides of the bottom of the adjusting plate 2 are provided with pulleys 14, and the pulleys 14 are tumblingly connected to the upper surface of the guide rail 7; a bracket 15 is fixedly connected to the top of the adjusting plate 2, and a second lead screw 16 is threadedly connected to the middle of the bracket 15; a lower pressure plate 17 is rotatably connected to the bottom of the second lead screw 16; and two symmetrically distributed positioning rods 18 are fixedly connected to the top of the lower pressure plate 17, and the positioning rods 18 slide through the inside of the bracket 15 on both sides.

[0030] During the process of fixing the steel workpiece, the second lead screw 16 is first rotated to move up and down in the middle of the bracket 15. Since the bottom of the second lead screw 16 and the top of the lower pressure plate 17 are connected to each other, the movement of the second lead screw 16 will drive the lower pressure plate 17 to move up and down. In addition, the movement of the lower pressure plate 17 will drive the positioning rod 18 to slide inside the bracket 15, thereby maintaining the stability of the up and down movement of the lower pressure plate 17. The steel workpiece is clamped and fixed by the downward movement of the lower pressure plate 17.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
